commit 8ea4e92945d312bd5d19714e070f695230037660 Author: Kristof Provost <[email protected]> AuthorDate: 2026-08-07 12:39:59 +0000 Commit: Kristof Provost <[email protected]> CommitDate: 2026-08-08 09:02:34 +0000 net: don't panic on ifconfig pfsync0 mtu 9000 pfsync interfaces do not have ifp->if_inet6 set, so when we update the MTU for those interfaces we panicked. Add an explicit check for this. This should be temporary, until pfsync is no longer a struct ifnet (as we've already done for pflog).
